Chrome for iOS has recently been updated and as Google does with version numbers, they kept this release in line with the other Chrome releases. In other words, Chrome for iOS version 21.0.1180.77 is now available in the iOS App Store. And aside from a silly looking version number, this Chrome app update has brought a few changes, additions and fixes. The changelog notes that there has been some stability and security improvements as well as “many” bug fixes. Perhaps more exciting to most users though, Chrome for iOS now allows for sharing of web pages over Google+, Facebook and Twitter. With that, Chrome for iOS is a universal app and requires iOS 4.3 or later for use.
